Chelsea skipper John Terry was pleased to leave Wearside with three points after a professional display against the Black Cats.
The England international defender opened the scoring for Andre Villas-Boas' side, his second goal in as many visits to the Stadium of Light, before Daniel Sturridge doubled the Blues' advantage.
Whilst disappointed to concede a late consolation goal to Ji Dong-Won, the fast start was key to claiming all three points in the 2-1 win, and Terry believes there are plenty of positives that the Blues can continue to build-on ahead of their European campaign starting in earnest tomorrow night (Tuesday).
"We had a good pre season but we have not played as well as we'd have liked in the first three games, but we showed on Saturday what we are getting to in terms of our targets and the way we want to play. I am very pleased. Naturally it will take time but we are getting there," Terry told the official Chelsea website.
"It was very pleasing for me personally. I scored at Sunderland last season as well and I was delighted to get the goal. We started the game very well and having got the goal early on, we kept control of the game in the second half as well. The second goal was crucial for us as well and when we got that, with the game in mind on Tuesday we maybe dropped the tempo a little bit.
"We are disappointed we conceded late on but the main thing was starting well and getting three points and we went home very happy."
Raul Meireles impressed for the Blues on debut, setting up Sturridge for the second goal, whilst summer signing Oriol Romeu also tasted senior action with the club for the first time.
Terry believes these are all signs that things are looking good at Stamford Bridge, with competition for places fiercer than ever under their Portuguese manager.
"It is very good. It reminds me of three or four years ago," he continued.
"We have a big squad and everyone fighting for places and with the Champions League and the Carling Cup starting soon, we have a lot of games coming up so I wouldn't be surprised if we saw a bit of rotation as well."
